A method of making an implantable device includes directing a projection of laser energy having a plurality of adjacent energy pixels on a build surface atop a bed of powder, thereby forming a layer of the implantable device. The directing step is repeated a plurality of times, in a layer-by-layer manner, such that a totality of the formed layers define at least a portion of the implantable device.

A component of a plasma processing chamber having a coating on at least one surface that comprises yttrium aluminum. The coating is an aerosol deposited coating from a powder mixture of an yttrium oxide powder and an aluminum-containing powder and having an yttrium to aluminum ratio of 4:1 to 1:4 by molar number. The coating can be annealed to form a porous ternary oxide.

The invention relates to a method for manufacturing an epilame mechanical part (2) comprising a substrate (4) made of a first material, the method comprising at least:

a step (10) of depositing an epilame product (6) consisting of a second material on the substrate (4), said deposition being carried out in the form of a projection onto the substrate (4) of at least one collimated or localised beam (12; 12A, 12B) of material containing the epilame product (6); and

a step (11) of treating the second material to ensure the cohesion of the components on the substrate (4).

The invention relates to a device and method for preparing a structure or object using an additive manufacturing process referred to as sequential cold spray laser sintering. The method includes depositing by cold spraying a plurality of sequential layers of material onto a substrate/build plate or particles of materials onto a compacted powder bed of material and employing an energy source to sinter or melt each of the plurality of sequential layers or powders to produce sequential sintered layers, wherein the number of additional layers is determined based on those needed to produce the final structure.

The disclosure includes manufacturing a semimanufactured cylinder head (3) having a shielding curtain portion (16g) and spraying metal powder (P) onto an annular valve seat portion (16f) using a cold spray method to form a valve seat film (16b). The shielding curtain portion (16g) projects in an annular shape from an annular edge portion of an opening portion (16a) of an intake port (16) or an opening portion (17a) of an exhaust port (17) toward the center (C) of the port. The annular valve seat portion (16f) is located on an outer side of the port than the shielding curtain portion (16g).

Disclosed is a method for manufacturing free-standing cladding tubes with multi-layer structures. According to the method, a cylindrical mandrel substrate defining a hollow cylindrical inner space is provided. A first cold spray powder metal is selected. The cylindrical mandrel substrate is rotated and the first cold spray powder metal is applied to an outer surface of the cylindrical mandrel substrate to form a first layer. The cylindrical mandrel substrate is removed.
